Be it known that I, WILL M J. STERN- eu, a citizen of the United States, residing,

at: Benton Harbor, in the ceunty of Berrien I and: State QfMichigan, have invented certain n w a d useful Improvements i Loosel- Legtf Binders, of which the follgwinglis, 3;

The proportion and relation of the parts are liftingfthe ball carrier to its readily be done by means of the collar 12) the releasing lever can be disengaged and.

removed or replaced, although invthe normal use of the mechanism it is not liable to accidental disengagement.

t a may be readily disengaged, however, by lifting the bar while presslng, with diseni. practically without resistance, even other bar face,

gaged fingers, upon the releasing lever.

Since the clutching mechanism permits the bar to slide downwardly upon the posts, though thereleasing lever be leftfree', I have provided means for yieldingly maintainingflthe bar in elevated position, consisting of a pair of balls 16 confined within a transverse bore in'the top member of the binding post and stressed apart by a spring 17 The opposite margins of theorifice are slightly constricted by a suitable'tool after the balls have been inserted, permitting a portion of each ball to project into the path of the margin of the orifice through the clamping bar members 2 and 3. A slight degree of positive force may be applied toforce the clamping bar past theballs, while the tension of the sprlng is suflicient to'maintain the bar in upper positionuntil such force is applied in order to overcome its resistance. I claim: i 1. In a loose leaf binder having covers and hingedly connected clamping bars, one of said bars being-equipped with binder posts, clutching mechanism carried by the arranged to cooperate with the posts, and comprising a wedge block seated in such bar and having a conical wedging a plurality of balls arrangedto cooperate therewith, carrier arranged to stress said balls into engagement with saidwedging face, and a rocking lever operable to shift said carrier and balls into position of disengagement. v

2. In a loose leaf binder having covers and hingedly connected clamping bars, one of said bars being equipped with binder posts, clutching mechanism carried by the. other bar arrangedto cooperate with the posts, and comprising a wedge block seated in such barand having a conical wed'gingfa'ce, a plurality of balls arranged to cooperate a spring-pressed balltherewith, a springpressed ball-carrier arranged to stress said balls into engagement with said wedging face, said carrier having a radially extending collar at its outer end, and a rocking lever having a forked end ar ranged, to cooperate with said collar and a finger piece at its opposite end operable to shift said carrier and balls into position of disengagement.

3. In a loose leaf binder having covers and hingedly connected clamping bars, one of said bars being equipped 'with binder parts, clutching mechanism carried by the other bar arranged to cooperate with the posts and including a wedge block seated in said bar and having an inclined wedging face, ball clutching means operate with said wedge block, a springpressed, ball-carrier arranged to stress said ball-clutching means into engagement with said wedging face, and a rocking release lever fulcrumed upon the outer face of said last-mentioned bar and having one end arranged to cooperate with said ball-carrier and having its other end formed to serve as a finger piece. 7 v
